DESCRIPTION
The 1261-21-xx Type 2 Surge Protection Device (SPD) is designed for protection of downstream
distribution equipment and wiring as well as most sensitive electrical and electronic loads from the
effects of overvoltage transients that might be produced from lightning, induction, load or power
factor capacitor switching. Multiple LEDs indicate the functional status of the protection elements
within the suppressor.
Model 1261-21-TNC is suitable for use on TN-C and TN-C-S power systems (see EN60950).
Model 1261-21-TNS is intended for TNS power systems, but it may be used on TN-C-S and U.S.
120/240V (without neutral) services as well.
Model 1261-21-TT is intended for TT systems, but it may be used on TNS, TN-C-S, and U.S.
(without neutral) services.
Model 1261-21-IT is intended for IT systems, but with caution may be used on the above other
power systems as well.
Operation
1. Apply power to the panel. If the electrical and grounding wirings are done correctly, the
green function status LED will illuminate. If the LED is not on, remove the power and
review all of the previous installation procedures.
2. If after a known heavy lightning strike has occurred and the LED is off, reset the breaker.
If the function LED lights come back on then the protector is fine. If the light is still out,
or you can not reset the breaker, the protector must be replaced. This unit contains no user
serviceable parts.

Important Safety Instructions
All work must be performed by qualified electrical personnel. The electrical system must be properly
grounded in accordance with applicable codes for this suppressor to work correctly. The 1261-21-xx
Type 2 SPD must be connected behind a 30A maximum breaker on a system that has a short circuit
current rating of 100kAIC maximum.

Installation
The unit must be installed in parallel to the electrical distribution system on the load side of
the main service disconnect behind a 30A maximum breaker. Careful consideration should
be made in selecting the knockout location because excess lead length and sharp bends in
the wire drastically decrease the effectiveness of the SPD. For this reason choose a knockout location
that minimizes lead length and sharp bends. The SPD may also be mounted by it's metal bracket
within the equipment enclosure.

Disconnect all power supplying the electrical panel
Remove the panel screws and cover. Retain these parts for re-installation.
Either remove a knockout 0.5 inches (13mm) or install provided metal bracket
Remove lock washer from the SPDs threaded nipple. Carefully feed the wires through to
avoid cutting wire insulation. Slide lock washer over the wires to anchor the threaded
nipple. Rotate the SPD so that the function status LED indicators can be easily viewed.
Tighten the lock washer to secure the SPD.
Locate the neutral bar inside the electrical panel and connect the blue wire to the neutral bar
and tighten to torque specified on inside of panel. Keep conductor length as short as possible and
avoid sharp bends in the wire.
Locate the ground bar inside the electrical panel. Connect the green/yellow wire to the
ground bar and tighten the terminal to the torque specified on the panel. Keep conductor
length as short as possible and avoid sharp bends. If neutral is bonded to ground, green
wire may be terminated to neutral.
Brown wire to be connected to a 30A maximum breaker. Tighten terminal to torque
specified on inside of panel. Keep lead length as short as possible and avoid sharp bends.
Re-install panel cover.
